H&R 70258-28 Sport Sway Bar Front 28mm Anti-Roll Bar Kit

The H&R 70258-28 is a front sport sway bar (anti-roll bar) engineered to reduce body roll, increase lateral stiffness, and deliver sharper cornering performance. Designed for drivers who want improved handling without sacrificing ride quality, this 28mm front sway bar is a direct-fit upgrade over the factory unit.

Premium 50CrV4 Steel Construction:

• Crafted from high-tensile 50CrV4 spring steel alloy — stronger and more resilient than OEM and most competitive sway bars
• Each bar is cold-formed and heat-treated for maximum durability and consistent performance
• Shot-peened to increase surface hardness, extend service life, and verify dimensional accuracy
• Finished with a powder coat for long-lasting corrosion resistance and clean appearance

Precision-Engineered Design:

• Formed on proprietary H&R machinery to ensure an exact, application-specific fit
• Features smooth, machined-like forged seamless bar ends that allow for stiffness adjustability on select applications
• Increases suspension roll stiffness — resistance to body lean in corners — while maintaining everyday ride comfort

Exclusive Urethane/Teflon Composite Bushings Included:

• Proprietary bushing design features a molded-in fabric-like Urethane/Teflon composite
• Eliminates squeaking without any lubrication or ongoing maintenance
• No mess, no grease — just install and drive

Like all H&R suspension components, this sway bar is 100% manufactured in Germany at an ISO 9001 certified facility, ensuring consistent quality and performance in every unit. Pairs perfectly with H&R springs, coilovers, and cup kits for a complete handling upgrade.
